Moore, one half of the R&B duo Sam & Dave, announced Tuesday he’ll be appearing at the “Make America Great Again! Welcome Celebration” in Washington on the eve of the Jan. 20 inauguration.

"As an American, I am honored to perform for President-elect Donald Trump," Moore said in a statement. "I was a participant in the civil rights movement and have seen many positive changes and advancement in my 81 years of living in this wonderful country, but I know we must all join hands and work together with our new president,” the Grammy Hall of Famer and “Hold On, I’m Comin’ ” singer said.

“I honestly believe that if we can accomplish this, the best is yet to come. We all as Americans need to unite behind our new president and give him a chance. He needs everyone’s support to make America greater, stronger and an even better country,” 81-year-old Moore said.

The addition of Moore — who’s performed multiple times for President Obama at the White House — comes just days after Broadway veteran Holliday suddenly cancelled an already-announced performance at the inaugural festivities, saying she desired to “stand with the LGBT community.”

“See what he brings to the table,” Moore said of Trump, during a chat with ITK last month.
